Abstract

Various intensifications of potato cultivation, such as the provision of paclobutrazol and nitrogen (N) fertilizer, are thought to impact the quality of the seeds produced. This study aims to evaluate the effects of different N fertilizer doses and paclobutrazol concentrations applied in the preharvest period on the sprouting performance of G0 potato tuber seeds after storage. Nine treatment combinations, each repeated three times, were tested, using 50%, 100%, and 150% of the recommended N dose and paclobutrazol concentrations of 50, 100, and 150 part per million (ppm), applied at 30 and 45 days after planting, respectively. The interaction effect between N fertilizer and paclobutrazol concentration was not significantly affected on all observed variables. Preharvest application of 100% N fertilizer produced the largest seedlings, indicated by the highest shoot length at 56 and 74 days after storage. Preharvest application of 150 ppm paclobutrazol produced the highest shoot length, shoot emergence rate, and seedling dry weight than other treatments. The present study implied the importance of preharvest N and paclobutrazol for improving the sprouting performance of G0 potato seed tuber.

Abstract

Job's tears is a cereal crop that has beneficial nutrients. Potassium is known to affect the growth and yield of cereal crops, but there has been limited study on whether potassium affects the nutrition and physical quality of Job’s tears seeds.  This study aimed to analyze the effect of K fertilizer on the nutritional content and physical quality of Job's tears seeds. This research was conducted from January to May 2024 at Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, Sumedang, Indonesia. This experiment used the Randomized Block Design (RBD) method with six treatments and four replications. Various doses of K fertilizer (KCl) were tested, i.e., 0, 62.5, 125, 250, 375, and 500 kg/ha KCl. The measured nutritional content was the extraction rates of carbohydrate, protein, lipid, calcium, and potassium, while the physical quality was represented by the weight of husked grain, size of seeds, and seed hardness. Results showed that potassium increased the extraction rates of carbohydrate, protein, lipid, calcium, and potassium. Potassium also increased the weight of husked grain and size of seeds. A dosage of 500 kg/ha KCl resulted in the best nutrition, weight of husked grain, and size of seeds.

Abstract

Appropriate land management has a long-term impact on soil performance and is believed to improve soil fertility. This study investigated the effect of eco-enzymes on soil nutrients and plant productivity of green mustard-peanut in inceptisol. The research was conducted from February to April 2025.  The experiment used a randomized block design (RBD) consisting of 5 treatments and replicated 3 times, so that there were 15 units, including N0 = without Eco-enzyme, N1 = Eco-enzyme 2cc/L. N2= Eco-enzyme 4cc/L, N3= Eco-enzyme 6cc/L, and N4= Eco-enzyme 8cc/L. The commodities used were green mustard (Brassica juncea L) and peanut (Arachis hypogaea Linn). Soil properties variables included soil pH, N-total, and P-available, while plant productivity variables included plant height, number of leaves, leaf area, fresh weight, and pod production. The results showed that the concentration of eco-enzymes had a significant effect on N-total, P-available, green mustard plant height, and peanut plant height. However, eco-enzyme concentration had no significant effect on soil pH, number of green mustard leaves, green mustard fresh weight, green mustard leaf area, number of peanut branches, and peanut pod production. The lowest production of green mustard was 0.85 tons/ha, and the highest was 3.29 tons/ha. While the lowest production of Peanut pods was 4.3 tons/ha and the highest was 6.67 tons/ha.

Abstract

Climate change, with global temperatures rising by 1.09°C from 1850–1900 to 2011–2020, threatens potato production, a critical staple crop, by exceeding the optimal temperature range of 15–20°C. This review synthesizes over 45 peer-reviewed studies published between 2015 and 2025 from Google Scholar and ScienceDirect to evaluate the physiological, morphological, and tuber quality responses of potatoes to high temperatures and to identify adaptive cultivation strategies for sustainable production. High temperatures reduce photosynthetic efficiency through chlorophyll degradation and stomatal closure, increase respiration, and divert photosynthates to vegetative growth, leading to 18–32% yield losses globally by the 2050s. Heat-tolerant varieties, such as Atlantic (11.47 tons/ha), Merbabu-17 (11.04 tons/ha), and Granola (3.61 tons/ha), maintain productivity in medium-altitude lands. Plant growth regulators (PGRs), including BAP, melatonin, and paclobutrazol, enhance tuber yield by regulating hormonal balance and antioxidant activity. Drip irrigation and mulching (e.g., straw, wheat, plastic films) improve water use efficiency and buffer soil temperature. These integrated strategies of heat-tolerant varieties, PGRs, irrigation, and mulching offer practical solutions to mitigate heat stress and ensure sustainable potato production under changing climate conditions.

Abstract

Soybeans are an important crop with high nutritional value and diverse uses. Current consumer and industry preference is for soybean varieties with large seeds and high productivity. To meet these demands, one effective approach is through hybridization. This study aims to evaluate the phenotype of F10 soybean line from a cross between Grobogan and Slamet for large-seeded and high-yield. The study was conducted in the screenhouse and Plant Breeding and Biotechnology Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The experiment used a Randomized Complete Block Design (RCBD) with three replications, testing genotypes from Slamet x Grobogan crosses and three check varieties: Slamet, Grobogan, and Wilis. Observational data were analyzed using analysis of variance (ANOVA) with a 5% error rate and continued with LSD to select lines with high-performing genotype. The results of the ANOVA showed that the tested lines affected growth parameters and plant yield components. LSD analysis showed that the highest leaf length and number of leaves were in GS 7. In seed weight per plant, all lines were below Grobogan, followed by GS 7 and GS 47. In 100 seed weight, all lines were below Grobogan, but there were lines with large seed categories (> 14 g/100 seeds), namely GS7, GS 12, GS 36, and GS 39. Correlation analysis showed that the number of pods and 100 seed weight were positively correlated with seed weight per plant. Therefore, these traits can be selection indicators to identify high-yielding soybean genotype.

Abstract

In recent years, productivity decline in arabica coffee has become a real issue in Indonesia. This decay has been brought about by various external and internal factors that are beyond human control. Various factors, including suboptimal cultivation practices, take part in this process. The objective of the present study was to evaluate the effect of pruning combined with foliar fertilizer application (coconut water and sugarcane molasses) and 6-benzylaminopurine (BAP) on the vegetative growth of arabica coffee plants during the production phase. The research was conducted at Ciparanje Experimental Field, Universitas Padjadjaran, using a randomized complete block design with seven treatments including a control (without pruning and foliar application), application of coconut water (75%, 750 mL L⁻¹), sugarcane molasses (2 mL L⁻¹), and BAP at 60 ppm, each applied with and without pruning, and four replications. In this research, the main parameters observed included the number and length of the lateral branches, leaf chlorophyll index, leaf area, canopy width, number of fruit clusters per branch and per tree, and coffee cherry fruit weight. It emerged that the combination of pruning and the use of sugarcane molasses at 2 ml/L significantly increased lateral branch formation, leaf area, and the number of fruit clusters per tree. The integration of pruning with foliar treatments effectively supported optimal growth of productive-phase arabica coffee plants.

Abstract

Developing a leaf-area estimation model for vegetable cultivars in wetlands is essential to optimizing agricultural cultivation practices. This study aims to develop a non-destructive model for leaf area estimation in wetland vegetable cultivars (velvetleaf (Limnocharis flava) and kangkong (Ipomoea aquatica)) using regression-based models. The plants were cultivated in a wetland system. Measurements of leaf length and width were taken on all leaves of each plant, using the product of length and width (L×W) as predictor. The regression models for estimating leaf area were adjusted from linear, zero-intercept linear, quadratic, and power. The optimal model was evaluated using the determination coefficient (R2) and the Root Mean Square Error (RMSE). The results showed that the most reliable regression model for estimating velvetleaf leaf area was linear regression with the equation y = 0.881LW - 7.615 (R2 = 0.954; RSME = 7.916), and the power model for kangkong leaf area, with the equation y = 0.9407LW0.9309 (R2 = 0.970; RSME = 1.695). Differences in leaf shape among plant species result in different accuracies of leaf area estimation models. Thus, the model should be useful to guide future research and practical applications in monitoring leaf growth and determining harvest time.

Abstract

This research aimed to optimize the growth of vanilla (Vanilla planifolia) cuttings in acid soils by modifying the growing media and applying several types of plant growth regulators (PGRs). Several types of PGRs, including synthetic compounds such as indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP), as well as natural extracts from shallot (Allium ascalonicum L.) and moringa leaves (Moringa oleifera), were tested to enhance plant performance in acid-growing conditions. The primary objectives were to determine the optimal soil amendment formula and the most effective PGR type for promoting vanilla growth, and to develop a measurable, easy-to-use PGR formulation accessible to farmers. The study was conducted experimentally using a randomized complete block design (RCBD) with the first factor being modified acid soil media and the second factor being the type of PGRs. The results showed that both 100 ppm BAP (Z2) and 10% shallot extract (Z3) significantly outperformed other PGR treatments across all parameters and observation times. For instance, Z2 produced the highest recorded values for internodes (15.11 internodes) at 90 DAP, number of leaves (10.26 leaves) at 60 DAP, total leaf area (413.74 cm²) at 90 DAP, and aerial roots (12.22 roots) at 90 DAP. Conversely, Z3 demonstrated superior performance in the number of leaves (15.56 leaves) at 90 DAP and total leaf area (421.95 cm²) at 90 DAP. This treatment can be recommended as an effective strategy for enhancing the establishment of vanilla cuttings in acidic soil conditions.

Abstract

The medicinal plant Gymnema sylvestre is widely known for its ability to lower blood sugar levels. This study reviewed the physical characteristics and bioactive compounds of G. sylvestre sourced from different regions, emphasizing its potential as an antidiabetic agent. Morphological analysis includes leaf structure, trichome presence, and other anatomical features, which can influence the plant's chemical profile. Phytochemical analysis, performed using techniques like GC-MS, identifies key bioactive compounds such as saponins, flavonoids, and gymnemic acids, which contribute to its hypoglycemic effect. The findings indicate that regional variations can affect the concentration and presence of these compounds, suggesting that environmental factors and genetic diversity play significant roles. This comprehensive characterization supports the use of G. sylvestre as a natural antidiabetic treatment, which supports its potential as a source of antidiabetic-related bioactive compounds. Further research is recommended to explore the pharmacological mechanisms and optimize the extraction methods for maximum efficacy.

Abstract

Groundcherry (Physalis angulata L.) is a plant with many medicinal potentials due to its rich secondary metabolites such as phenolic and flavonoid. However, conventional agriculture practices are still limited, especially in Indonesia. This study was divided into two stages. The first stage was conducted to determine optimal 6-BAP and 2,4-D combination for callus induction, while the second stage was conducted to determine callus phenolic, flavonoid, and antioxidant response to salinity stress. The first stage was arranged in factorial completely randomized design with two factors: 6-BAP (0, 2, and 4 mg/L) and 2,4-D (0, 0.5, 1, and 1.5 mg/L). The second stage was arranged in simple completely randomized design with different NaCl concentration (0, 25, 50, 75, 100 mM) as treatments. The results showed significant interaction (p < 0.05) between 6-BAP and 2,4-D on callus induction. Combination of 2 mg/L 6-BAP and 1 mg/L 2,4-D showed the highest callus formation percentage (46% increase), callus size (60.12% increase), and fresh weight (179.69% increase), and greener compact callus. Application of NaCl as salinity stress at second stage experiment served as an elicitor to enhance callus antioxidant capacity. Salinity level at 100 mM NaCl showed the most accumulation of phenolic content (17.8% increase), flavonoid content (25.17% increase), and antioxidant activities (6.84% IC50 decrease). This study demonstrates plant growth regulator optimization with salinity stress elicitation integration as an effective strategy to enhance antioxidant production in P. angulata callus, providing a practical approach for controlled secondary metabolite production.
